This apparatus uses cladding to cover the inner surfaces of a door frame. The cladding also overlaps the door nose and its mounting screws. Two-sided adhesive tape on one edge of the cladding attaches the cladding to the door nose. The cladding has a perpendicular integral fin which extends into an opposed mating slit parallel to the door frame edge in the door frame inner surface. This combination aligns the cladding parallel to the door frame and holds theh cladding in place against tangential forces. An outwardly extending groove from the edge of the door frame opposite the door nose and parallel to the edge terminates in a keyway. The edge of the cladding opposite the nose has an perpendicular inset, which is sized to fit within the groove in the door frame. The inset terminates in an inwardly directed projecting key. The end of this key is pointed to engage the door frame keyway to hold that edge of the cladding securely in place.

Cladding apparatus for covering a generally U-shaped opening in the outer wall of a structure, the door frame having inner surfaces about and perpendicular to the opening which is sized to receive a door, the door frame also having adjoining inner and outer surfaces which are perpendicular to the inner surface, the outer surface having a door nose which cover the entire surface, the door frame being prepared by having slits in the inner surfaces which are parallel to the adjoining inner and outer surfaces and extend inward perpendicular to the doorway inner surface, having keyways in the adjoining inner surfaces which are parallel to the inner surfaces and extend inward perpendicular to the adjoining inner surface, and having grooves in the adjoining inner surfaces which extend parallel to the inner surface from the inner surface to the keyway, the cladding apparatus comprising a rectangular sheet of rigid material having an inset of a predetermined length and width which extends from an edge of said sheet perpendicular to said sheet in a first direction, said inset terminating in a key means for engaging a keyway, the sheet also having a fin of a predetermined length and width extending in the first direction perpendicular to the surface of said sheet, the dimensions and spacing of said inset said fin and the arrangement of said key means being such that said sheet will cover the inner surface of the door frame and a predetermined portion of the door nose with the insert fitting within the groove in the adjoining inner surface, with the key means engaging the keyway in the adjoining inner surface, and with the fin engaging the slit in the inner surface.
